Erfahren Sie, wie Sie mithilfe von Azurite automatisierte Tests für private Endpunkte für Azure BLOB Storage Emulator schreiben.Learn how to write automated tests against private endpoints for Azure Blob Storage by using the Azurite storage emulator.

Alongside the release of the new recursive access control list (ACL) APIs, Storage Explorer has a new feature called 'Propagate Access Control Lists'. You can use this feature to propagate the current ACLs of a folder to all of its existing file and folder descendants. You can choose to configure the storage emulator to access a local instance of SQL Server instead of the LocalDB instance as shown below. For more information, please refer to How the storage emulator works. When you have attach the local storage emulator to work with azure storage explorer for development and testing. Azure Storage Explorer. Now you can install the storage explorer application to view the storage data. From the application, you will be able to view Azure storage in the cloud (SAS) and your emulator storage services. I think the combination of the emulator and the storage explorer make for a nice cost-efficient development environment.

Authorization for tools and SDKs

Connect to Azurite from Azure Storage SDKs or tools, like Azure Storage Explorer, by using any authentication strategy. Authentication is required. Azurite supports authorization with OAuth, Shared Key, and shared access signatures (SAS). Azurite also supports anonymous access to public containers.

If you're using the Azure SDKs, start Azurite with the --oauth basic and --cert --key/--pwd options.

Well-known storage account and key

Azurite accepts the same well-known account and key used by the legacy Azure Storage Emulator.

• Account name: devstoreaccount1
• Account key: Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw

Custom storage accounts and keys

Azurite supports custom storage account names and keys by setting the AZURITE_ACCOUNTS environment variable in the following format: account1:key1[:key2];account2:key1[:key2];....

For example, use a custom storage account that has one key:

Or use multiple storage accounts with two keys each:

Azure Storage Explorer Vs Emulator

Azurite refreshes custom account names and keys from the environment variable every minute by default. With this feature, you can dynamically rotate the account key, or add new storage accounts without restarting Azurite.

Note

The default devstoreaccount1 storage account is disabled when you set custom storage accounts.

Connection strings

The easiest way to connect to Azurite from your application is to configure a connection string in your application's configuration file that references the shortcut UseDevelopmentStorage=true. Here's an example of a connection string in an app.config file:

HTTP connection strings

You can pass the following connection strings to the Azure SDKs or tools, like Azure CLI 2.0 or Storage Explorer.

The full connection string is:

DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw;BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;QueueEndpoint=http://127.0.0.1:10001/devstoreaccount1;

To connect to the blob service only, the connection string is:

DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw;BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;

To connect to the queue service only, the connection string is:

DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw;QueueEndpoint=http://127.0.0.1:10001/devstoreaccount1;

HTTPS connection strings

The full HTTPS connection string is:

DefaultEndpointsProtocol=https;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw;BlobEndpoint=https://127.0.0.1:10000/devstoreaccount1;QueueEndpoint=https://127.0.0.1:10001/devstoreaccount1;

To use the blob service only, the HTTPS connection string is:

DefaultEndpointsProtocol=https;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw;BlobEndpoint=https://127.0.0.1:10000/devstoreaccount1;

To use the queue service only, the HTTPS connection string is:

DefaultEndpointsProtocol=https;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw;QueueEndpoint=https://127.0.0.1:10001/devstoreaccount1;

If you used dotnet dev-certs to generate your self-signed certificate, use the following connection string.

DefaultEndpointsProtocol=https;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw;BlobEndpoint=https://localhost:10000/devstoreaccount1;QueueEndpoint=https://localhost:10001/devstoreaccount1;

Update the connection string when using custom storage accounts and keys.

For more information, see Configure Azure Storage connection strings.

Azure SDKs

To use Azurite with the Azure SDKs, use OAuth and HTTPS options:

Azure Blob Storage

You can then instantiate a BlobContainerClient, BlobServiceClient, or BlobClient.

Azure Queue Storage

You can also instantiate a QueueClient or QueueServiceClient.

Microsoft Azure Storage Explorer

You can use Storage Explorer to view the data stored in Azurite.

Connect to Azurite using HTTP

In Storage Explorer, connect to Azurite by following these steps:

2. Select Add an account
3. Select Attach to a local emulator
4. Select Next
5. Edit the Display name field to a name of your choice
6. Select Next again
7. Select Connect

Connect to Azurite using HTTPS

By default Storage Explorer won't open an HTTPS endpoint that uses a self-signed certificate. If you're running Azurite with HTTPS, you're likely using a self-signed certificate. In Storage Explorer, import SSL certificates via the Edit -> SSL Certificates -> Import Certificates dialog.

Import Certificate to Storage Explorer

1. Find the certificate on your local machine.
2. In Storage Explorer, go to Edit -> SSL Certificates -> Import Certificates and import your certificate.

If you don't import a certificate, you'll get an error:

unable to verify the first certificate or self signed certificate in chain

1. Select Toggle Explorer
2. Select Local & Attached
3. Right-click on Storage Accounts and select Connect to Azure Storage.
4. Select Use a connection string
5. Select Next.
6. Enter a value in the Display name field.
7. Enter the HTTPS connection string from the previous section of this document
8. Select Next
9. Select Connect

Workspace structure

The following files and folders may be created in the workspace location when initializing Azurite.

• __blobstorage__ - Directory containing Azurite blob service persisted binary data
• __queuestorage__ - Directory containing Azurite queue service persisted binary data
• __azurite_db_blob__.json - Azurite blob service metadata file
• __azurite_db_blob_extent__.json - Azurite blob service extent metadata file
• __azurite_db_queue__.json - Azurite queue service metadata file
• __azurite_db_queue_extent__.json - Azurite queue service extent metadata file

To clean up Azurite, delete above files and folders and restart the emulator.

Differences between Azurite and Azure Storage

There are functional differences between a local instance of Azurite and an Azure Storage account in the cloud.

Endpoint and connection URL

The service endpoints for Azurite are different from the endpoints of an Azure Storage account. The local computer doesn't do domain name resolution, requiring Azurite endpoints to be local addresses.

When you address a resource in an Azure Storage account, the account name is part of the URI host name. The resource being addressed is part of the URI path:

<http|https>://<account-name>.<service-name>.core.windows.net/<resource-path>

The following URI is a valid address for a blob in an Azure Storage account:

https://myaccount.blob.core.windows.net/mycontainer/myblob.txt

Since the local computer doesn't do domain name resolution, the account name is part of the URI path instead of the host name. Use the following URI format for a resource in Azurite:

http://<local-machine-address>:<port>/<account-name>/<resource-path>

The following address might be used for accessing a blob in Azurite:

http://127.0.0.1:10000/myaccount/mycontainer/myblob.txt

Scaling and performance

Azurite doesn't support large numbers of connected clients. There's no performance guarantee. Azurite is intended for development and testing purposes.

Error handling

Azurite is aligned with Azure Storage error handling logic, but there are differences. For example, error messages may be different, while error status codes align.

RA-GRS

Azurite supports read-access geo-redundant replication (RA-GRS). For storage resources, access the secondary location by appending -secondary to the account name. For example, the following address might be used for accessing a blob using the read-only secondary in Azurite:

http://127.0.0.1:10000/devstoreaccount1-secondary/mycontainer/myblob.txt

Table support

Support for tables in Azurite is currently under development and open to contribution! For the latest progress, check the Azurite V3 Table project.

Support for durable functions requires tables.

Azurite is open-source

Contributions and suggestions for Azurite are welcome. Go to the Azurite GitHub project page or GitHub issues for milestones and work items we're tracking for upcoming features and bug fixes. Detailed work items are also tracked in GitHub.
